Visible light-driven aerobic oxidation catalyzed by a diiron(IV) μ-oxo biscorrole complex
•We report a new photocatalyst for aerobic oxidations using molecular oxygen and sunlight.•We examine the reaction conditions and explore the substrate scope.•We report the evidence of detecting the key oxidizing intermediate.•The observed oxidation photocatalysis is ascribed to a photo-disproportionation mechanism.
Under visible light irradiation, the diiron(IV) μ-oxo-bis(5,10,15-tripentafluorophenylcorrole) complex catalyzes the aerobic oxidations of hydrocarbons in sequences employing photo-disproportionation reactions. The active oxidant, highly reactive corrole-iron(V)-oxo species, can be detected in real time via laser flash photolysis methods.
